- During my routine morning trip to the restroom I noticed I had started my period. The functional zone of my uterus was sloughing off and this would take about 3-5 days. Throughout the week I felt weaker and weaker and noticed I lost weight. I had to change my pad 10 times a day. By the end of the week I felt like a hollowed out shell and when I woke up on the 10th morning I was nothing but a pool of blood on my bed.
